I honestly just think it’s ignorance and/or plain idiocy. One of my closest friends who’s not dumb by any means, bought a home with his gf when homes were highly overvalued but loan rates were still on a record low (European country). I asked him if it was really such a good idea or if they could just rent or keep living seperately for a while longer - but no.

Well, when everything caught up and their rate doubled all of a sudden it’s hard to make their economy work (luckily they get by and are both educated but the rates can’t go much higher before shit hits the fan).

He later had to get a new car and could barely afford a 20yo used car and complained that it’s hard to have money left after all costs of living and I, like a good (bad?) friend, discreetly (not very much) brought up the fact that I “told him so”. His response was “yes I know but those are the rules we just have to play by and it’s out of our control”.
